Human Risk: Why Your Employees Are Your Biggest Cyber Threat… and Your Best Defence

Published on

6 November 2025

Human risk… from clicking on a phishing link to reusing passwords or mishandling sensitive data, even well-meaning employees can open the door to costly cyber incidents. The good news? With the right culture, training, and technology, your people can also become your most powerful layer of protection.

When most business owners think about cybersecurity, they picture firewalls, antivirus software, and IT teams monitoring for suspicious activity. But the truth is, the biggest risk to your organisation isn’t sitting in a dark room behind a screen, it’s sitting at a desk inside your office.

At Ashdown Solutions, we believe cybersecurity is as much about people as it is about technology, and here’s why.

The Human Factor in Cybersecurity

It’s easy to underestimate how big a role human behaviour plays in cyber incidents. According to multiple studies, around 80–90% of data breaches involve human error in some form. That might be a staff member falling for a fake invoice email, sharing credentials on a social platform, or forgetting to lock their laptop before leaving a café.

Cybercriminals know this and they exploit it. Instead of trying to “hack” into secure systems, they hack people. This tactic, known as social engineering, is designed to manipulate emotions like urgency, trust, or fear.

Common examples include:

  • Phishing emails posing as trusted contacts or suppliers.
  • Business email compromise (BEC) scams impersonating directors or finance staff.
  • Vishing and smishing, using phone calls or text messages to trick employees.
  • Tailgating or USB baiting, where attackers physically access premises or devices.

Even with advanced technical defences in place, one mistaken click can bypass them all.

Why Human Risk Is a Business Risk

The consequences of a cyber incident go far beyond IT downtime. For small and medium-sized businesses, the impact can be devastating:

  • Financial loss: from fraudulent payments or ransomware demands.
  • Operational disruption: halting sales, projects, or customer services.
  • Reputational damage: loss of client trust and future business.
  • Regulatory penalties: under laws like the UK GDPR for mishandling data.

In other words, cybersecurity isn’t just an IT issue, it’s a business issue. And managing human risk should be part of every organisation’s resilience strategy

Turning the Weakest Link into the Strongest Defence

So how do you turn your employees into your first line of defence rather than your biggest vulnerability?

Here are some key steps:

1. Build a Security-Aware Culture

Security starts with mindset. Encourage staff to question unexpected emails, verify requests, and feel comfortable reporting mistakes without blame. A culture of openness and vigilance is far more effective than one of fear or silence.

2. Provide Regular, Realistic Training

One-off training sessions don’t work. Cyber threats evolve constantly, so your team’s awareness should too.
Ashdown Solutions offers ongoing cybersecurity awareness programmes that use real-world examples and simulated phishing tests to keep staff alert and confident in spotting scams.

3. Implement Clear Policies and Procedures

Define how data should be handled, what to do in the event of a suspected breach, and how to report suspicious activity. The simpler and clearer your processes are, the more likely staff will follow them.

4. Use Technology to Support, Not Replace, Humans

Technical controls like multi-factor authentication (MFA), password managers, and endpoint protection tools are crucial, but they should complement, not replace, user awareness.

5. Lead from the Top

Security culture starts with leadership. When business owners and managers take cybersecurity seriously, employees follow suit. It should be part of every strategic discussion, not just an IT afterthought
